P3X-888 is the Tau'ri designation for the homeworld of a race known as the Unas. This world is also the only planet where Goa'uld larvae have been discovered in 'the wild' which, in addition to the fact that the Unas were the first race that the Goa'uld ever took as hosts, is the reason it is generally believed that this planet is also the Goa'uld homeworld. (SG1: "The First Ones")

Goa'uld still exist in the primordial waters, from which they once lept to take Unas as their first hosts. From there, they discovered the workings of the Stargate and left the planet — though Goa'uld and Unas still reside there in a hostile tension.

It should be noted, there is no naquadah in the blood of these Goa'uld. It's possible these Goa'uld are not entirely malevolent and may not be entirely sentient either, as the Goa'ulds that took SG team members as hosts did not seem to retain full control and did not seem to have any agenda other than the goal of inhabiting their host.

Behind the scenesEdit

Stargate SG-1: The DVD Collection issue 26 gives an alternate address for this planet () but, as Stargate SG-1: The Ultimate Visual Guide was produced at a later date, it can be assumed that this address has been overwritten.
